[0025] The hydraulic cylinder 7 first pushes the connecting plate 5 and the first mold 2 to move, so that the first mold 2 is combined with the second mold 3, and then the user can inject plastic into the inside of the forming cavity 8 for molding. After the raw material is molded, the output end of the hydraulic cylinder 7 pulls the connecting plate 5, so that the connecting plate 5 slides along the guide rod 6, drives the first mold 2 to move, and separates the first mold 2 from the second mold 3. Then the air cylinder 412 is started first, the air cylinder 412 pushes the temporary storage box 403 and the push plate 406 to move, the push plate 406 pushes the raw material to demold and discharge, and at the same time the rod body of the rotating rod 405 enters the inside of the forming cavity 8. Then the external water pump is started, and at the same time the valve for water flow is opened. Then the water flows through the shunt pipe 418, the hose 417 into the transmission groove 413, and then flows into the temporary storage box 403 through the connecting pipe 416. The water in the temporary storage box 403 flows through the first through hole 408 into the temporary storage groove 407 of the rotating rod 405, and then is sprayed out from the second through hole 409 on one side of the forming cavity 8 to flush the inside of the forming cavity 8.

Then the rotating rod 405 changes the water spraying angle by rotating to realize omnidirectional flushing of the inside of the forming cavity 8, so that each corner of the forming cavity 8 can be cleaned, and the cleaning effect is greatly improved.

[0026] After the flushing is completed, the water pump and the valve corresponding thereto are closed, and the drying fan and the valve corresponding thereto are started. The drying gas enters the transmission groove 413 through the shunt pipe 418 and the hose 417, and then enters the temporary storage box 403 through the connecting pipe 416. Then the drying gas enters the forming cavity 8 through the first through hole 408, the temporary storage groove 407 and the second through hole 409 to dry the forming cavity 8. At the same time, when the gas flows in the transmission groove 413, the fan blade 415 rotates, the fan blade 415 drives the rotating shaft 414 connected thereto to rotate, the rotating shaft 414 drives the upper rotating rod 405 to rotate, and the upper rotating rod 405 drives the lower rotating rod 405 to rotate synchronously through the sprocket 410 and the chain 411. Then the rotating rod 405 changes the blowing angle of the drying gas by rotating, which significantly shortens the cleaning and drying time, improves the overall processing efficiency of the plastic mold, makes the mold can be put into use faster for the next production, and reduces the idle time of the equipment.

[0027] The waste water generated in the flushing process is discharged through the drain pipe 9 installed through the rear end inside the support 1, so that the forming cavity 8 will not accumulate water, avoiding corrosion of the mold caused by accumulated water, prolonging the service life of the mold, and keeping the working environment clean;

[0028] After the drying is completed, the air cylinder 412 is started, the output end of the air cylinder 412 pulls the temporary storage box 403 to reset, and then the rotating rod 405, the temporary storage box 403 and the push plate 406 return to the initial position, and then the hydraulic cylinder 7 is started again to make the first mold 2 and the second mold 3 re-clamp, and the mold returns to the production state, ready for the next production.

[0029] The working principle of the plastic mold convenient to clean is as follows:

[0030] In use, first, the hydraulic cylinder 7 pushes the connecting plate 5 and the first mold 2 to move, so that the first mold 2 and the second mold 3 are clamped, and then the user can inject the plastic into the inside of the forming cavity 8 for molding, and then after the raw material is molded, the output end of the hydraulic cylinder 7 pulls the connecting plate 5 to make the connecting plate 5 slide along the guide rod 6, drive the first mold 2 to move, and separate the first mold 2 from the second mold 3, and then the air cylinder 412 is started to push the temporary storage box 403 and the push plate 406 to move, so that the push plate 406 pushes the raw material to demold and discharge, and at the same time, the rod body of the rotating rod 405 enters the inside of the forming cavity 8, and then the external water pump is started, and at the same time, the valve for water flow is opened, and then the water flows into the transmission groove 413 through the shunt pipe 418 and the hose 417, and then flows into the temporary storage box 403 through the connecting pipe 416, and then the water in the temporary storage box 403 flows into the temporary storage groove 407 of the rotating rod 405 through the first through hole 408, and then is sprayed out from the second through hole 409 on one side of the forming cavity 8 to flush the inside of the forming cavity 8, and at the same time, when the water flows in the transmission groove 413, the fan blade 415 is rotated to drive the rotating shaft 414 connected thereto to rotate, and the rotating shaft 414 drives the upper rotating rod 405 to rotate, and the upper rotating rod 405 drives the lower rotating rod 405 to rotate synchronously through the sprocket 410 and the chain 411, and then the rotating rod 405 changes the water spraying angle by rotating to realize the omnibearing flushing of the inside of the forming cavity 8.

[0031] After the flushing is completed, the water pump and the valve corresponding thereto are closed, and then the drying fan and the valve corresponding thereto are started to make the drying gas flow into the transmission groove 413 through the shunt pipe 418 and the hose 417, and then flow into the temporary storage box 403 through the connecting pipe 416, and then flow into the forming cavity 8 through the first through hole 408, the temporary storage groove 407 and the second through hole 409 to dry the forming cavity 8, and at the same time, when the gas flows in the transmission groove 413, the fan blade 415 is rotated to drive the rotating shaft 414 connected thereto to rotate, and the rotating shaft 414 drives the upper rotating rod 405 to rotate, and the upper rotating rod 405 drives the lower rotating rod 405 to rotate synchronously through the sprocket 410 and the chain 411, and then the rotating rod 405 changes the blowing angle of the drying gas by rotating to realize the omnibearing drying of the inside of the forming cavity 8.

[0032] After the drying is completed, the air cylinder 412 is started, the output end of the air cylinder 412 pulls the temporary storage box 403 to reset, then the rotating rod 405, the temporary storage box 403 and the push plate 406 return to the initial position, and then the hydraulic cylinder 7 is started again, so that the first mold 2 and the second mold 3 are re-clamped, and the mold returns to the production state, thereby preparing for the next production.
